A network engineer is writing a NETCONF filter to retrieve interfaces that have a element OR a element, but not both. Which XPath expression correctly implements this exclusive OR logic?

//interface[description and disable]

//interface[description or disable]

//interface[description xor disable]

//interface[description and not(disable)] or //interface[disable and not(description)]

A network engineer needs to retrieve the second element of each that has at least two children. The Junos configuration has multiple interfaces, each with multiple units. Which XPath expression selects the second of every interface that has at least two units?

//interface[count(unit) >= 2]/unit[2]

//interface[position()=2]/unit[2]

In a NETCONF get-config operation, what is the role of an XPath filter?

It specifies which parts of the configuration to retrieve

It transforms the configuration into a different format

It defines the order in which configuration data is returned

It validates the configuration before retrieval

In an XPath expression, how do you handle an XML namespace that is defined with a prefix like ?

Use a wildcard for the namespace, e.g., /*:configuration

Use the namespace URI in the expression, e.g., /{http://example.com}configuration

Ignore the namespace and use the local name only, e.g., /configuration

Use the namespace prefix in the XPath expression, e.g., /junos:configuration

A network operator needs to retrieve all interfaces whose description does NOT contain the word 'backup'. The description is stored in the child element. Which XPath expression correctly filters these interfaces?

//interface[description != 'backup']

//interface[not(description = 'backup')]

//interface[not(contains(description, 'backup'))]

//interface[contains(description, 'backup')]

Part of the NETCONF and XML API domain, which makes up ~20% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~7–12 in this domain), expect 2–3 from this objective — we provide 16 practice questions to prepare you well beyond it.
